EX-Action: Automatically Extracting Threat Actions from Cyber Threat Intelligence Report Based on Multimodal Learning
Algorithm 1
Threat actions identification.
| Require: | Input: | Training Set: ; is the candidate action of machine identification, is the action feature value, which contains 9 values | is the action of manual extraction | Base classification learners: | : | for each do | for each do | is the predicted value of action in the Base classification Learners | end for | is the weighted of action in the Base classification Learners | if is the action weight, is the optimal voting threshold then | is the selected action set | is the similarity of the action between the ground truth and machine identification | end if | if is the optimal similarity threshold then | is correct action | end if | end for | Output: |
